"solim (class-2,10 i v when said fitting is placed in waste stackitthe IGenerically this'yinvention relatesto a' fitting used inplumbing systemsand especially ingconnection with bath tubs, water closets, wash of asiriglecasting forplumbing stack fitting known to the} trade as a gangfitting and is a combined closet and bath waste and vent fitting minimumof space andto save labor in installation. j

Animportant object of this invention is the provision of a plumbingstack fitting made in a single form knownasaT and also in adouble, formknown'asa cross or code-cross adapted to eliminate extra vents with acomparatively small, openingfor bathtubconnections,"and below, a

large opening for closet bowl outlet, and so posilarge lower openingpointing directly tofcloset bowl outlet, the upper smaller bath openingis automatically on a direct linewithbath* tub waste'ftherebyeliminating extra ventsfcalking joints and bends :heretofore required,andwalso designed to save time and labor'in installation to conceal theplumbing pipes, etc.

j In :Fig. 1 there is, showna washbasin bowl 2, bath tub- 3, and stackwaste line 4.

in connection: with the furring of ceiling in order I The portionof'thejstack or main soil line as shown in Fig. 1 comprises sections(floodecross Section I, and section8. Section-6 is*posi5 tioned astoeliminate calked joints and bendsheretoforeirequired in waste fittings.e i One of the principal objects of this invention isthe provisionof aplumbing fitting comprising waste passage, lower large closet wastepassage extending at right angles'from said m ainpassag e and uppersmallersimilarly extending bathwaste an integral casting formed with amain soil' or passage communicating with said mainfpassage,

the upper part of said main passageacting asa vent to preventsiphonageof bath traps, thereby eliminating extra vents, the relative positionsof said upper and lower passages being such that when the fittingisoperatively positioned in the wardly from diametrically oppositesides ofpormain soil or stack line, calkedjoints, bends and extrafconnectionsare eliminated. i

With these and other objects in viewi 'which \villbecome apparent as thedescription proceeds,"

theinvention resides in the construction; conibination and arrangementof parts hereinafter morefully described and claimed, andillustrated inthe accompanying drawing, in which like cha'r acters of referenceindicate like parts. throughout the several figures, of which:

,, Fig, l is a similar view showing the arrange} ment with my improved Tor code-cross fitting. Fig. 2 is an elevation of my improved fitting.

the lower end of section 5 as will be well understood i i i My improvedcode-cross section 1 comprises "a vertically extending pipe or mainbodlyportion l6 terminating at its upper end in the elongated hubahd flangeportions [1 and I8, respectively,

and at its lower end in flange 19. Spaced above its lower end section 1is formedwithbranches 20 extending substantially at right angles outtion16 and terminating in the enlarged hub and fiange,'sections 2| and 22,respectively, aridcon stituting the closet openings 22 as willhhereinAbove the branches 20 in substantial vertical alignment therewith andextending irompipe l6 are thediametrically opposite branches 23formedwith the right angularly extending portions '24 terminating inthe-enlarged hub portions 25 projecting at right anglesto hub portionsHand constituting bath openings 25" of smaller diameterthan' openings22. IThe'branches from the right angular extendingportions 2.4 adjacenthubs} .25 expand downwardly to} section W at points immediately above Abranches ;20 forn1ing the inwardly and, downwardly inclined walls Z6.

This construction provides large ppienings at points (of intersectionwiththe main body por tion It and terminates in the comparatively smallopenings 25' located above thelarg'e closet openings 22' and connectedto section IBso that'the upper part of said section acts as'a ventand pivents the bathjtrapfZ'I from siphoning; swni directly more fully appear.Code-crosssection 1 I; closet i mounted under floor 9 with hub portion Hextending above the floor and adapted to receive the lower end ofsection 6 as clearly shown in Fig/. the lower end extending through theceiling 28 sembly, as shown in Fig. 1, located on the op posite side ofa partition Wall not shown. The

trap 21 is suitably connected to the outlet of bath 1 3, and, by asuitable pipe 3| to inlet opening 25"; the free end of which is adaptedto be received ing in time and labor incident to installation, and

.desire, protected by Letters Patent is as set forth by hub and efiectscommunication with said bath opening 25' as will be clear withoutfurther discussion. In this connection it will bevnoted that branches2!) and 23 are connected by the ver tical web 32 which unites them intoa unitary structure. l a

eglltfw ll be noted that where only one-bath in stallation is'necessary, branches 2!! and 23 on one sideof thecode-cross 1 may beplugged, therebytconstituting in effect a single or T -fitting, or aelj' casting formed with said branches on one side 11, fitting iscompact, and Fig. 1' shows how the closet and bath can be connected tothe. single stack, waste and vent line 4 within the space between 10'?joists, that being the distance between floor} and ceiling 28, andconstituting a sanitary installation,-,and eliminating the vent or ventsand the necessity of furring the ceiling below, as requiredin connectionwith the prevailing con struotions. r a

.,.' .;It,Wil1 be apparent that I have constructed a plumbing fittingadapted to occupy a minimum of space and which, is a combined closet,bath waste, and vent fitting comprising an integral casting,

thelsmalhbath openings being placed above th e largecloset openings andconnected to the main body section I6 so that the upper part of, saidsection acts as a vent and prevents siphonageof bathtrapsor traps. Suchconstructionnot only afiords the advantages above noted but alsoeliminates additional vent piping, heretofore in use, as well asseparate vents forthe bath traps.

the relation of the closet. and bath openin gs, and their location aresuch that when the Tor code-cross fitting is operatively positioned the"stack or main soil line with the lower large ol inings'pointing directlyto, the closet bowl outletthe upper small opening is automaticallpositioned in a direct line for connection with the bath waste outlet,thereby eliminatingthe calked joints and bends heretofore required.

i From the above it will be apparent that by the use of my improvedfitting the vent heretofore prevalent is eliminated as Well as the addedex pense for vents for the respective-bath traps, and by my constructionthe portion of the main body onstem disposed above the bath branchesacts as a ventto prevent siphonage of the bath trap, and the relativepositions and arrangement of the bath and closet branch outlets is suchthat when thefitting is operatively positioned in the soil line,forinstance, with the large closet inlet opening facing the closet outlet,the bath inlet will be in a direct line with the bath trap outlet,there'- by "eliminating the prevailing calked joints and bends, and inaddition I have provided an integral fitting, simple in construction,manufacturable 'or expense, adaptedto effect a savthe bath branch actingtherewith as a vent to.

may be installed, and in either case the eflicient for the purposesintended.

Although in' practice it has been found that the form of the inventionillustrated in the accompanying drawing and referred to in the abovedescription as the preferred embodiment is the most efficient andpractical; yet realizing the conditions concurrent with the adoption ofthe invention will necessarily vary, I desire to empha sizethatvariousminor changes in details of construction, proportion and arrangement ofparts, may be resorted to withinthe scope of the appended claims withoutdeparting from or sacrificing any of the principles of this invention.

Having. thus, described my invention; what I in the following claims:
